dont play up her shafted romantic status for the love of god. ive seen way too many roxys that focus on the fact that she's got no current romantic prospects because dirk and jane are gunning for the same guy. dont make her all about wanting to get in dirks pants or jakes pants or hell even janes pants and then angsting because she cant. yes she's lonely but shes not going to shove it in their faces or focus on it all the time especially if she's in a game with other available people. roxy is all about her friends and their problems.

also be creative with her typos. dont copypaste from canon. hell maybe just try typing faster than you normally do and dont hit backspace. get carried away with metaphors and be creative.

if you take her from her drinking stage focus on the fact that she drinks because she's lonely and has a lot of problems and buries that under her party girl personality because she doesnt want people to worry. and actually research alcoholism.
